In this hands-on activity, students learn about the different realms of the Universe and explore their sizes and relative scales. They will be guided through a process that uncovers the immense sizes of the Sun, Solar System, Solar Neighborhood,...(View More) Milky Way, Local Group, Supercluster, and the observable Universe. The full version of this activity involves students doing simple math computations, however it can also be done without the math. There are some inexpensive materials involved, as well as a powerpoint presentation. It is intended for grades 8-12, but can be adapted down for lower grade levels.(View Less)

In this activity, students are introduced to light and colored gels (filters). Students make and test predictions about light and color using gels; learn about the importance of gels (filters) to astronomers; then analyze images taken with regular...(View More) and infrared cameras to see that objects opaque to light at one wavelength, may be transparent to light of a different wavelength. Section 1 of the activity guide includes teacher notes, information on materials and preparation, student misconceptions, and a student pre-test. Each activity section also includes teacher notes, student activity sheets, and answer keys. This activity is the first of four activities in Active Astronomy, which are designed to complement instruction on the electromagnetic spectrum, focusing on infrared light.(View Less)

In this activity, students build a photocell detector, and use it to detect different colors of light in a spectrum. Then they place the detector just outside the red region of the visible light spectrum and see that the detector detects the...(View More) presence of light there, even though there is no color visible. Students learn that invisible light exists and that we can detect this light with instruments other than our eyes. In a final part of the activity, students investigate the infrared signals emitted by TV and VCR remote controls. The activities build upon each other and are best taught in order. Section 1 of the activity guide includes teacher notes, information on materials and preparation, student misconceptions and a student pre-test. Each activity section also includes teacher notes, student activity sheets, and answer keys. This activity requires some special materials (e.g. a small solar cell, alligator clip leads, plus common classroom materials (e.g., overhead or slide projector). This activity is the second of four activities in Active Astronomy, which are designed to complement instruction on the electromagnetic spectrum, focusing on infrared light.(View Less)

This is an activity about the size and scale of the Sun, Earth and Moon. Learners will collectively paint and label a model of the Sun and determine the comparative sizes of these three bodies. Learners can then complete a worksheet to further...(View More) explore the mathematical concepts of less than, greater than, and equal to. This activity will require various materials of specific measurements to ensure accuracy. This is Activity 3 of a larger resource entitled Eye on the Sky.(View Less)

This is an activity exploring the concept that distance affects how we perceive an object's size, specifically pertaining to the size of the Sun and the Moon as seen from Earth. Learners will complete a hands on activity where two balls of differing...(View More) sizes stand in for the Sun and the Moon. By moving the balls away from each other, students will determine how far the larger ball needs to be in order to make the two seem similar in size. They will also use the balls to demonstrate a solar eclipse. Lastly, learners will complete a worksheet explaining their findings. This is Activity 12 of a larger resource entitled Eye on the Sky.(View Less)

This is an activity to reinforce concepts learned about the Sun, the Sun, Earth, and Moon system and eclipses. Learners will communally discuss their knowledge of these concepts briefly, and will then complete a series of worksheets and writings to...(View More) demonstrate grasp of content. This is Activity 15, the final activity of a larger resouce entitled Eye on the Sky and is meant to follow the preceding 14 activities in the resource. These worksheets and writings would ideally be added to students' portfolios accumulated throughout this suite of lessons and can serve as a summative assessment of student work throughout the lesson suite.(View Less)

This is an activity about shadows and how the Sun's location affects the direction of a shadow. Learners will first identify what they already know about shadows and will be asked to share any questions they may have. Then students will be taken...(View More) outside to observe and trace a classmates shadow. From this tracing, students will complete a worksheet by drawing their partner, his or her shadow, and the location of the Sun. Two to three hours later, this observation and tracing process will be repeated, allowing students to witness the movement of shadows as a result of the Earth's rotation. This activity requires a sunny day with plenty of outdoor space to trace the shadows of all students. This is Activity 4 of a larger resource entitled Eye on the Sky.(View Less)

This is an activity about the Sun, Earth and Moon and their movements during solar and lunar eclipses. Students observe and manipulate a styrofoam ball model and simulate the movement of these bodies during the different kinds of eclipses. Learners...(View More) will also complete a worksheet to reinforce understanding of this model and concept. This activity requires a location with an open space approximately ten feet by ten feet in area, and is Activity 11 of a larger resource entitled Eye on the Sky.(View Less)

This interactive, online activity allows students to examine the Hubble Deep Field image and simulate the process astronomers have gone through to classify the objects in it. Students classify select objects in the image based on observable...(View More) properties such as color and shape. Students then compare their classifications to those made by astronomers. Upon completion of this activity, students will have classified objects in the Hubble Deep Field, described their characteristics, and used a table to display their data. Students can work through the activity independently or in groups. Teachers also may choose to have students prepare oral reports based on what they learned after performing the activity. Detailed teacher pages, identified as Teaching Tips on the title page of the activity, provide science background information, lesson plan ideas, related resources, and alignment with national education standards. This activity is part of the online exploration "The Hubble Deep Field Academy" that is available on the Amazing Space website.(View Less)
